More details on the Yamaha RX-V681
Features & specs
Yamaha's Total Purity Concept: The Yamaha RX-V681 AV Receiver incorporates Yamaha's Total Purity Concept for the finest sound quality. The Total Purity Concept, which Yamaha has been cultivating for many years, encompasses high drive amp technology, high purity pre-amplification, anti-vibration technology, and independent pure power supplies. As a result, this AV receiver can provide high-quality sound for your movie & music soundtracks.
- High Drive Amp Technology: A fully discrete power amplifier helps maximize sound and minimize distortion of the receiver. The Yamaha RX-V681 AV Receiver is equipped with a 7-channel amplifier rated at 80 watts (into 8-ohms, at 20-20kHz, with 0.09% THD, driving 2 channels) which provides high dynamic power with low-impedance drive capability.
- High Purity Pre-Amplification: The Yamaha RX-V681 uses high quality, audio-grade Burr-Brown 192kHz/24-bit digital-to-analog converters for all channels to maximize sound quality. The AV receiver also utilizes low-jitter PLL circuitry to help optimize sound imaging. The result is a more dynamic sound with greater detail and less distortion.
- Anti-Vibration Technology: The AV receiver's anti-vibration heatsinks suppress vibration from transistors and sound pressure.
- Independent Power Supplies: Independent power supplies are used for the receiver's analog and digital circuitry to prevent digital noise from affecting analog circuitry.
Intelligent Amplifier Assignment: Intelligent Amp Assignment automatically assigns amplifier channels of the Yamaha AV receiver to certain speakers depending on what speaker layout has been selected and what content is being played back. You can connect up to nine speakers to the AV receiver and it will determine which seven speakers need amplification. You can choose from a variety of amplifier speaker layout configurations.
- Basic Surround: In this configuration, up to nine speakers (Front L/R, Front Presence L/R, Center, Surround L/R, & Surround Back L/R) can be connected to the AV receiver. When Cinema DSP 3D is on or a Dolby Atmos soundtrack is being played, the two Front Presence speakers will be powered and not the two Surround Back speakers. When Cinema DSP 3D is off or Dolby Atmos is not playing, this situation is reversed and the Front Presence speaker turn off while the Surround Back speakers are powered. Bi-amp and Zone 2 speakers are not available in this mode.
- Dolby Atmos + Zone 2: In this setup, you can hook up a 5.1.2ch Dolby Atmos speaker system in the main room and a pair of speakers in Zone 2 to the receiver. When Zone 2 is off, all seven channels of your Dolby Atmos speaker system will be powered. However, when Zone 2 is turned on, power to the Front Height, Overhead, or Dolby Atmos speakers will be cut off and directed to the pair of speakers in Zone; limiting you to only 5.1ch surround in the main room. Bi-amp & Surround Back speakers are not available in this setup.
- 7ch + Zone 2: In this configuration, up to nine speakers (Front L/R, Center, Surround L/R, Surround Back L/R, and Zone 2) can be connected to the AV receiver. When Zone 2 is off, all seven channels will be used in the Main Zone. However, when Zone 2 is on, power to the two surround back channels will be directed to the two speakers in Zone 2 and the Main Zone will receive five channels of power. The same or different analog input sources/volume settings can be applied to both zones. Bi-amp, Front Presence, & Dolby Atmos speakers are not available in this mode.
- 5ch Bi-Amp: Up to five speakers (Front L/R, Center, & Surround L/R) can be connected to the AV receiver. The Surround Back amplifier channels of the AV receiver are reassigned to bi-amp the front speakers. A bi-amplification connection uses two amplifiers for one speaker. One amplifier is connected to the woofer section of a loudspeaker while the other is connected to the combined midrange and tweeter section. With this arrangement each amplifier operates over a limited frequency range, making its job easier. Zone 2, Front Presence, & Dolby Atmos speakers are not available in this mode.
YPAO Sound Optimization: This unit employs the YPAO (Yamaha Parametric Acoustic Optimizer), which automatically adjusts the output of the speakers based on placement, performance, and the room's acoustic characteristics. Yamaha's YPAO system uses a small microphone and sophisticated equalization to automatically set the best sound for any room, no matter where the speakers are. First it checks the speaker connections and phase of each speaker. Then it sends out tones which are captured by the microphone to analyze the room acoustics and sets a variety of parameters; such as the speaker size, the distance of the speakers, and even the volume level; until it achieves the best sound conditions for your room. Using the supplied Optimizer Microphone, YPAO performs the following checks and makes appropriate adjustments to give you the best possible sound from your system
- Speaker Check: YPAO checks which speakers are connected and the polarity of each, checks the frequency response of each speaker and sets the appropriate crossover frequency for each channel, checks the distance of each speaker from the listening position and adjusts the delay of each channel, as well as checks and adjusts the volume level of each speaker.
- R.S.C (Reflected Sound Control): The receiver also employs YPAO's Reflected Sound Control (RSC) to correct early reflections for studio-quality sound.
- EQ: Choose between 3 YPAO EQ modes - Natural (adjusts all speakers to a natural sound; useful when the flat setting sounds too bright), Flat (use when all the speakers in the system have similar sound characteristics), or Front (EQs the center and rear speakers to sound like the front; useful when your front speakers are better than the others in the system)
- DSP Effect Normalization: In addition, YPAO provides DSP Effect Normalization, which varies the Cinema DSP parameters according to the reflected sounds in the room.
- YPAO Volume: Human ears have less sensitivity to high and low frequencies, especially at lower volumes. YPAO Volume applies loudness EQ correction to automatically adjust high and low frequency levels as volume changes. Using the YPAO measurement results, EQ correction is optimized to your system settings and listening environment.
Note: You can also choose to manually adjust the AV receiver's speaker, crossover, & EQ settings.

Immersive Surround Sound: The Yamaha RX-V681 AV receiver goes beyond regular surround with the latest immersive surround sound formats, including Dolby Atmos & DTS:X (future firmware update required for DTS:X).
- Dolby Atmos: The Yamaha AV receiver will enhance properly designed systems with Dolby Atmos where sound comes alive from all directions, including overhead, to fill the home theater with astonishing clarity, power, detail and depth. The RX-V681 has the processing power to run a more enveloping 5.1.2ch Dolby Atmos layout utilizing front-height, ceiling mounted, or Dolby Atmos-enabled speakers (sold separately). A 5.1.2 speaker configuration is based upon a traditional 5.1 speaker layout complemented by two Front Height, Overhead, or Dolby Atmos-enabled speakers.
- DTS:X: DTS:X is the next generation object-based, multi-dimensional audio technology from DTS. Unbound from channels, DTS:X conveys the fluid movement of sound to create an incredibly rich, realistic and immersive soundscape - in front of, behind, beside and above the audience - more accurately than ever before. DTS:X offers the ability to automatically adapt the audio to the speaker layout that best fits your space.
Post Decoding Formats: The Yamaha AV receiver supports Dolby Surround, DTS Neural:X, and DTS Neo:6 (Music/Cinema) to enhance 2-channel and multichannel decoding formats.
- Dolby Surround: Dolby Surround offers an enhanced cinema experience to your 2ch and multichannel movie soundtracks using your existing 5.1ch, 7.1ch or Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".
- DTS Neural:X: DTS:X incorporates Neural:X, the latest spatial remapping technology from DTS, which provides a fully immersive output for all types of source content; this includes DTS bitstreams and non-encoded (PCM) data. Neural:X delivers a thrilling sense of immersive sound to your speaker layout regardless of the original source format.
- DTS Neo:6: DTS Neo:6 is an advanced matrix decoder that takes any two-channel source (including television broadcasts, CDs and DVDs) and expands it into five or six channels. It also provides separate, optimized modes for stereo music materials and matrix surround motion picture soundtracks. DTS Neo:6 brings you a more revealing sound from ordinary stereo and a more expansive home cinema experience.
Cinema DSP Soundfields: Conventional multichannel audio reproduction systems base their sound on Dolby Digital and DTS decoding, using matrix and steering technologies to create surround sound effects. Yamaha Cinema DSP is much more advanced, actually creating richly realized independent soundfields that envelop you in an unmatched surround sound experience. With dialog, music and effects ideally located in these separate soundfields, you will hear sound with accurate placement, smooth movement, exceptional clarity and richness, and realistic presence. It will seem as if the walls of your room have disappeared and you are in the middle of your own immense theater. The AV receiver offers 17 Cinema DSP programs for movies, music, and games.
- Movie Soundfields: Standard, Spectacle, Sci-Fi, Adventure, Drama, Mono Movie, Sports, Action Game, Role Playing Game
- Music Soundfields: Hall Munich, Hall in Vienna, Chamber, Cellar Club, The Roxy Theater, The Bottom Line, Music Video, 7ch Stereo
Cinema DSP Modes: The Yamaha RX-V681 AV receiver offers proprietary Yamaha Cinema modes so you can enjoy your movies and music even more in your home; regardless if you are using 5.1 speaker setup, only have a two-channel speaker system, or listening through headphones.
- Cinema DSP 3D: The actually measured soundfield data in
recorded soundtracks contain the information of the height of the sound
images. Cinema DSP 3D mode achieves the reproduction of the accurate height
of theses sound images so that it can create the accurate and intensive
stereoscopic soundfield in your listening room. The receiver achieves Cinema
DSP 3D through its virtual Presence Speaker & Virtual Surround Back Speakers
- Virtual Presence Speaker (VPS): With the power of CINEMA DSP 3D, the Virtual Presence Speaker function makes full use of center and surround speakers to create audible information from where presence (height) speakers are normally installed.
- Virtual Surround Back Speaker (VSBS): This receiver also features a Virtual Surround Back Speaker function. Even without using surround back speakers, you can experience more natural, lifelike sound from behind you without physical speakers being installed in the surround back area of the listening environment.
- Virtual Cinema DSP: Virtual Cinema DSP is an algorithm that allows you to enjoy DSP soundfield surround effects while using a minimal two-speaker system. Virtual Cinema DSP lets you enjoy the effects of Cinema DSP surround sound without using surround speakers (handy for use in custom installations where some rooms don't have surround speakers). It can be used with the front/center speakers or even with just the two front left and right speakers. This unit will switch to virtual Cinema DSP mode automatically when surround speakers are unavailable.
- Virtual Cinema Front: With Virtual Cinema Front, you will enjoy virtual 5-channel surround sound with higher quality and resolution by installing surround speakers at the front. You get more flexibility to arrange your speakers inside the room, along with easy enjoyment of high quality surround sound.
- Silent Cinema: Silent Cinema makes it possible to hear large-scale surround sound through ordinary headphones. This is a variation of Cinema DSP technology that Yamaha developed to let you listen in private to movies and other multi-channel sources for hours without listening fatigue.
CINEMA DSP Parameters: You can adjust the following parameters of the Cinema DSP modes.
- DSP Level: You can change the receiver's CINEMA DSP effect level (level of the soundfield effect to be added). You can adjust the level of the soundfield effect from -6 dB to +3 dB.
- Delay: Adjusts the delay between the direct sound and the presence soundfield (1-99ms), surround soundfield (1-49ms), and surround back soundfield (1-49ms).
- Room Size: Adjusts the broadening effect (0.1-2.0) of the presence soundfield, surround soundfield, and the surround back sound field.
- Liveness: Adjusts the loss (0-10) of the presence soundfield, surround back soundfield, and surround back soundfield.
- Reverb: Adjusts the delay time of the rear reverberant sound (1.0-5.0s), the delay between the direct sound and rear reverberant sound (0-250ms), and the volume of the reverberant sound (0-100%).
HiFi Sound Modes: The Yamaha RX-V681 offers two HiFi audio modes which bypass the receiver's tone & DSP processing for higher sound quality performance. These HiFi sound modes lets you play back input sources without any soundfield effect processing. When either of theses modes are enabled, each speaker produces its own channel audio signal (without soundfield processing). When playing back 2-channle sources, such as a CD player, stereo sound is heard from the front speakers. When playing back multichannel sources, the receiver produces unprocessed multichannel surround sound.
- Straight: 2-channel stereo sources are output from only the front left and right speakers, while multi-channel sources are decoded straight into the appropriate channels without any additional tone or DSP processing.
- Pure Direct: Turns off the surround and tone circuitry, and dims the front-panel display, allowing sources to bypass the decoders and DSP processors of this unit so you can enjoy pure hi-fi sound from 2-channel or multi-channel sources. During Pure Direct playback no sound is output from the subwoofer.
Compressed Music Enhancer: Yamaha employs sophisticated digital signal processing with exclusive algorithms to enable playback that improves the performance of compressed music formats, including MP3, WMA, & AAC. The Yamaha receiver's Compressed Music Enhancer feature is even optimized for Bluetooth wireless audio streaming. With the Compressed Music Enhancer, highs and especially lows are richer and smoother, bringing music back to life to be as close to the original as possible.
Dialog Lift, Level, & Control: Dialog Lift raises the sound of dialogue from the center speaker to a position in the center of the screen. Newly developed virtual dialogue lift achieves dialogue lift function even without the need for presence speakers. Dialog Level Adjustment lets you control the volume of the vocal sound, so you hear movie dialog and music vocals at the ideal level for clear, comfortable listening. DTS Dialog Control allows you to boost the dialog to make dialog more intelligible in noisy environments.
Center-Channel Adjustment: When using the Dolby Surround mode, you can adjust the "Center Spread" to spread the center channel signals to the left and right front speakers. When in DTS Neo:6 Music mode, you can adjust the "Center Image" to broaden the effect level of the center-channel on the front soundfield.
Dynamic Range Control: The Yamaha RX-V681 employs two Dynamic Range Control functions.
- Adaptive DRC: Adaptive DRC automatically adjusts the dynamic range of the sound according to the volume level. This ensures that you hear clear dialog, vocals, and all sound effects at comfortable levels. There is no need to adjust the volume level as you listen; everything from whispers to big explosions will be heard clearly and comfortably at the same volume setting. It also tones down loud TV commercials and is ideal for low-volume, late-night listening when you do not want to disturb others.
- Dynamic Range: The amount of dynamic range compression applied to bitstream signals is adjustable; Min/Auto is suitable for low volume listening, Standard is typical for home use, and Max doesn't compress the dynamic range at all.
Bass Management: The Yamaha RX-V681 AV receiver provides the following Bass Management settings.
- Bass & Treble: You can adjust the balance of the high-frequency range (Treble) and low-frequency range (Bass) of sounds output from the receiver' front left and right speakers to obtain a desired tone. You can independently adjust the bass (50Hz) and treble (20kHz) from -6dB to +6dB in 0.5 dB increments. The tone control of the speakers or headphones can be set separately.
- Extra Bass: You can select whether to play front channel low-frequencies through either of the front speaker or the subwoofer, or through both the subwoofer and front speakers.
- Subwoofer Trim: The Subwoofer Trim control enhances the low frequencies by avoiding overlap with the front speaker output. This will result in a cleaner, more focused sound stage while providing a seamless frequency response. When subwoofer frequency overlap occurs in conventional systems, the overall sound is "pushed" toward the subwoofer. Subwoofer Trim takes care of this by separating the low subwoofer frequencies cleanly, thus stabilizing the front stage while providing a well-balanced enhanced bass sound.
Volume Setup: The Yamaha RX-V681 allows you to customize the receiver's volume levels.
- Volume Scale: You can choose to display the "Relative" volume scale (-80 to +16dB) or an "Absolute" volume scale (0 to 97).
- Max Volume Adjustment: Use this feature to set the receiver's maximum volume level. This feature is useful to avoid turning the volume too loud by mistake. You can set the Max Volume from -30dB to +15dB in 5dB steps, or to +16.5dB (full volume range is -80dB to +16.5 dB).
- Initial Volume Setting: Use this feature to set the volume level when the power is turned on. You can choose between Off (same as the volume when the unit was turned off), Mute, and -80dB to + 16.5dB in increments of 0.5dB.
- Volume Trim: Use this feature to adjust the volume level of each input. This is useful to balance the level of each input to avoid sudden changes in volume when switching between input sources. The range is from -6dB to +6dB in 0.5dB increments.
Phono Input: The Yamaha AV receiver features a dedicated Phono (MM) input for connecting your turntable and listening to your vinyl records.
Audio Outputs: The Yamaha RX-V681 AV receiver is fitted with binding-post speaker terminals and dual mono-sub/LFE outputs, along with a front-panel headphone jack.
- Speaker Terminals: The receiver has binding post terminals for the Front, Center, Surround, and Surround Back/Bi-Amp/Zone 2 speaker terminals. The Front Presence/Zone 2 speakers terminals are spring-clips. The binding posts can accept bare wire, pin connectors, and single banana plugs. These terminals are spaced too far apart for dual banana plugs and a collar surrounding them prevents the use of spade connectors. The spring-clip terminals only accept bare wire or pin-connectors. You can select 8 ohms or 6 ohms in the menu depending on your speaker application. The amplifier supports 4- to 8-ohm Front speakers, and 6- to 8-ohm Center and Surround speakers.
- Dual Sub Outputs: The Yamaha AV receiver includes dual LFE (mono-subwoofer) outputs for connecting up to two powered subs (parallel outputs; not discrete).
- Headphone Jack: The Yamaha RX-V681 is equipped with a front-panel 1/4" headphone jack for connecting a set of headphone, so you can listen to your music privately. Connecting a set of headphones automatically mutes the receiver's speaker outputs. Sound effects applied during playback can also be heard through the headphones.
HDMI 2.0a: The Yamaha RX-V681 AV receiver is fitted with six HDMI 2.0a inputs (5 rear/1 front) and one HDMI 2.0a output that support the latest HDMI standards; such as 4K/60Hz, 4:4:4 color subsampling, HDR (High Dynamic Range), Wide Color Gamut (BT.2020), and 21:9 aspect ratio. The receiver's HDMI 1-3 inputs and HDMI output also support HDCP 2.2 for full support of today's 4K content from Ultra HD Blu-ray, online video services (like Amazon & Netflix), and future TV broadcast services.
- 4K/60Hz: The RX-V681 supports up to 4K (3840x2160 pixels) video @ 60 frames per second on all of its HDMI inputs and output. It will also pass a 480i, 480p, 720p, 1080i, or 1080p video signal.
- HDCP 2.2: Only the receiver's HDMI 1-3 inputs and HDMI output support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission.
- 4:4:4 Color Subsampling: The receiver also supports RGB, YCbCr 4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color subsampling (@ 60Hz or 50Hz). With 4:4:4 color subsampling, luminance (brightness) and chroma (color) are sampled at the same rate; resulting in an RGB color palette as big as the video sampling rate for a video image with more colors, plus greater color accuracy and detail. The front-panel HDMI only supports 4K 60/50Hz using format YCbCr 4:2:0 only.
- HDR (High Dynamic Range): HDR (High Dynamic Range Video) provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth.
- Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a much wider color gamut and represents about 75% of the total visual color spectrum, while the current Rec. 709 color standard selected as the color space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the total visual color spectrum.
Note: Use a premium high-speed 18Gbps HDMI cable for the best 4K/HDR performance.
4K Video Upscaling: The Yamaha RX-V681 is capable of outstanding upscaling and i/p conversion quality. This AV Receiver will upscale video signals from analog (480i only)-to-HDMI and HDMI-to-HDMI, up to 4K. This means a much better picture with HDTVs capable of 720p, 1080i, 1080p, or 4K resolution.
Other HDMI Features: The Yamaha RX-V681 AV receiver's HDMI connectivity also offers 3D video pass-through, ARC (Audio Return Channel), Deep Color & x.v.Color support, as well as an auto LipSync function.
- 3D Ready: The Yamaha RX-V681 AV receiver supports 3D video pass-through (720p/1080p only) from connected 3D-compatible Blu-ray, games and broadcast devices to 3D-compatible HDTVs (all 3D components must be connected via HDMI). Special eyewear will be required for viewing 3D content.
- ARC (Audio Return Channel): This feature of the RX-V681's HDMI monitor output allows audio to be sent from your compatible HDTV to the receiver through the same HDMI cable already being used to send audio and video to your HDTV. This eliminates the need for extra cables connected to your television.
- Deep Color & x.v.Color Support: The AV receiver supports Deep Color and x.v.Color content, which can display a larger color range than standard-definition schemes. The result is a more lifelike, vibrant picture
- LipSync: This function adjusts the delay between audio and video output. You can do this manually or have the receiver set the LipSync function automatically. When connected to a TV via HDMI the receiver automatically adjusts audio output timing (0-500ms) if the TV supports an automatic LipSync function. You can also manually delay the sound output up to 500ms to synchronize it with the video image.
- Standby Through Mode: When the RX-V681 is in standby mode (power off), the Standby Through feature allows HDMI source signals to pass through the receiver to the TV. The HDMI input can be changed using the remote control. So, there's not need to turn on the AV receiver in order to switch HDMI sources.
Composite & Component Video: The RX-V681 AV receiver offers both composite and component analog video jacks. The RX-V681 offers two component video inputs and one component video monitor output. These jacks have a frequency response of 5 Hz to 60 MHz and will pass High Definition video sources up to 1080p. The receiver also features four composite video inputs and one composite video monitor output (480i only).
Background Audio/Video: The Background Video feature allows you to watch a video source while listening to a different audio source. With the RX-V681, you can select any video input (HDMI or analog) and listen to audio via the receiver's AM/FM tuner, Aux input, Network, or Bluetooth.
Wired or Wireless Network Connection: The Yamaha AV receiver is fitted with a RJ-45 Ethernet (LAN) port to connect the receiver to your home network.
